To me there is a list of "perfect storms" brewing and you could fill a couple pages about the ELE alone, so it is far beyond mere speculation.
It is rather gloomy and doomy. I have had a few discussions with people that have investigated and then grappled with the rather convincing evidence to this effect. We tend to agree that, due to the late states we are in, it is best for those who know enough to try to mitigate the impact on their lives and deal with the psychological impacts that will have. Conversely, I tend to leave anyone living in a bubble about it to whatever comforts them for now concerning all this. Sometimes it is just too big and complex to explain something that should already be clearly evident in the mainstream of society, facts and all.
The result? Well, those who are aware and grapple with it may have long, slow slog to the results, but they can prepare themselves and adapt as best as possible. Those who need to protect themselves mentally and emotionally will be better off over the short-term, but very susceptible to the eruptions and sudden shocks when it is on their doorstep, so to speak. There are pros and cons to both approaches on the individual level and collectively. There was a window of opportunity to really prevent this, but it is rapidly closing.
So, yes, the cold hard truth is quite disturbing and I just wanted to note one perspective on the two ways of looking at it at this stage and in regards to dealing with others. However, this all may be a ravaging cycle of changes and there are so many variables that I still can retain some optimism that pertains to potentials for either dealing with this better in the short-term or some sort of reversal in the far future, which all depends on the troubling question as to how far our species, (and the rest of the interdependent biosphere and its creatures) will make it. It seems to me that mitigating the effects of it all is even being given the priority it deserves now that stopping it or reversing it has become less viable.
